Sector antenna working in 5.9 GHz band with 18 dBi gain, dual polarizations for MIMO applications, Because of reduced sidelobes, antenna keeps clear strong signal even in crowded radio environments. Perfectly designed for operation under severe weather conditions. Proper materials allow operation in the salt water environments without corrosion. Professional mounting system with 0-15 degrees scale guarantees easy and smooth tilt down as well as rock-stable operation.
